2 Claims.

This invention relates to devices for applying adhesive markers or stickers to surfaces. It is especially adapted for marking charts or maps employed in various systems for keeping geographical records.

Ordinarily the system of marking maps is carried out by means of colored thumb tacks or push pins. One of the difiiculties from using tacks or pins is that the map must be backed with a rigid board and therefore cannot be rolled. A further difficulty arises when, due to vibration or accidental touching, the pins or tacks are loosened to the extent that they fall out and destroy the record. To overcome these difficulties 1 propose using a sticker in place of the pins or tacks.

An ordinary flexible paper sticker employing mucilage as the adhesive agent would serve to mark the record. However, it would be difficult to remove such a sticker from the surface of a paper map when a change in the record is desired without injuring the map. I have found that a sticker made of a hard elastic compound such as Celluloid may be readily removed from a paper surface without injuring it. In most cases the size of sticker required for marking is so small that it would be impractical to apply them to the surface by hand and for that reason I have provided the proposed device.

The main object of this invention is to provide a container for holding a plurality of the stickers made of any hard elastic compound and particularly the type of sticker I have described in my copending application filed at the same time this application was filed. The container portion of the device will bear a certain indicia or color similar to the indicia or color of the sticker, aiding in the selection of the pro-per mark to be fixed to any surface. A plunger is provided for ejecting the stickers from the container,

- and the contour of the internal bore of the container is so designed that only one sticker at a time may be ejected during the operation of marking a map or similar surface.

The general object of my invention is to provide a device for marking a surface with stickers in accordance with any proposed system of keeping records. Other objects and advantages of this invention will be pointed out in the description herebelow when read in conjunction with the drawing, in which- Fig. 1 is a front elevational view partially in section, showing my invention loaded with stickers. Fig, 2 is a top plan View of the same.

Fig. 3 is a top plan view, and Fig. 4 is a front elevational view of a single sticker.

Fig. 5 is an enlarged partial view illustrating the relative position of a sticker to the shoulder, at the time asticker is being applied to a surface.

In detail my invention comprises a cylindrical container l2 in combination with a plunger II. The stickers are stacked in the container l2 as indicated by I3, (Fig. l). The container is loaded through the upper open end at which point the internal bore is beveled as indicated at I4 to facilitate inserting the column of stickers. The bottom of the column of stickers I3 (Fig. 1) rests on the annular shoulder IS. The contracted internal bore of the container at the point of the annular shoulder I5 is slightly less than the outside diameter of the sticker. By applying a slight pressure on the plunger II the bottom sticker will be distorted due to its elasticity so'that it may be forced by the shoulder I5 to the position I6 (Fig. 1). Although the stickers l3 are illustrated as having a cylindrical side wall perpendicular to the bottom and top surfaces, as a matter of fact a slight burr is produced in the process of punching out the stickers from the original blanks. This lip or burr how ever works to the advantageof the device since it provides a more satisfactory bearing surface for cooperation with the annular shoulder IS in that the lower sticker may readily be forced by the shoulder when pressure is exerted on the plunger,

As illustrated in Fig. 5, surface l8 represents the division line between sticker Hi (the sticker being applied to a map surface) and sticker I! (the next sticker to be applied) and is in the same plane with the inner edge of the annular shoulder 15. The cylindrical container I2 is so designed that the distance between the line of the annular shoulder I5 (surface l8) and the base IQ of the container l2 is slightly less than the thickness of a sticker. Therefore when the container I2 is held firmly against a surface to which a sticker is being applied, pressure on the plunger II will move the column of stickers 13 downward thereby forcing the bottom sticker past the annular shoulder l5 against the map surface.

However, due to the fact that the distance between l8 and I9 is less than the thickness of each sticker, sticker ll cannot be forced past the shoulder l5 as long as sticker l6 remains under the base of the container. This limitation prevents the ejection of more than one sticker during a single operation of applying a sticker to a map.

The steps in the operation of the device for marking a surface with a sticker includes, first,

moistening the lower or adhesive surface of the sticker held b the shoulder l5 which would be sticker H of Fig. 5 (the bottom sticker I6 Fig. 5 having been previously removed by application to a map surface). The container i2 is then pressed firmly against a point on the surface to be marked and the plunger H forced downward. Ihe pressure on the plunger forces the sticker 11 past the shoulder I 5 into the position iii of Fig. 5. This operation presses the moistened adhesive surface of the sticker [6 against the map or chart leavin sticker I 6 fastened to the map surface; thereafter the container [2 is removed which leaves the second sticker (l1 Fig. 5) in the lower position resting on the shoulder I2 and ready for application to a surface in the next operation.

Although I intend to employ my invention with various sizes of stickers for general purposes I prefer to use a sticker having a diameter of 0.147 of an inch. With that size of sticker the long internal bore of the cylindrical container should be approximately 0.1485 of an inch in diameter while the opening or internal bore at the annular shoulder 15 should be approximately 0.146 of an inch in diameter. The plunger II is provided so as to form a running or sliding fit in the container. For any system of keeping records a separate container will be supplied filled with its respective color of sticker, the containers being loaded by the manufacturer.

I claim- 1. A device of the type described including a cylindrical container adapted to hold a plurality of stickers made of hard elastic material, an internal annular shoulder near the base of said container for supporting said stickers, said shoulder being located at a distance above the base of the container less than the thickness of a single sticker for preventing more than one sticker from being ejected from the container during each operation, and a plunger adapted to slide in said container for ejecting said stickers from the base thereof.

2. A device of the type described including a cylindrical container adapted to hold a plurality of stickers made of a hard elastic material, an internal annular shoulder located in said container at a distance above its base less than the thickness of a single sticker for preventing more than one sticker from being ejected from the container during each operation, the opening formed by said annular shoulder being slightly less than the outside diameter of said stickers, and a plunger adapted to slide in said container for forcing the stickers past said shoulder and ejecting said stickers from the base of the con tainer.
